After cooking the first 20 minutes, stir in tomato paste but not bacon. Transfer soup to two-2-quart freezer containers. Seal, label, and freeze up to 3 months. When ready to serve, transfer one portion of frozen soup to a large saucepan. Cover and cook over medium heat for 35 to 40 minutes or until bubbly, stirring occasionally to break up mixture. Sprinkle bacon over each serving. Makes 8 main-dish servings (two 4-serving portions).
